In my Patent No. 1,112,367 I have shown a device adapted to tie a Weavers knot. The device herein disclosed is primarily intended totie a weavers knot, but my invention is not in all aspects thereof limited to the tying of Such a knot. In its general organization, the knot tying device herein disclosed is similar to that disclosed in my said patent in that I employ two hooked needles which co-act to tic the threads into a knot, but instead of supporting the mechanism upon the hand of an operator, I provide a handle 4by which the device may be grasped, and

provide means whereby the device may be actuated by impingerncnt upon or against or in engagement 'with an extraneous object. Thereforc, the device is not digitly operated, but on the contrary, and in accordance with the disclosed embodiment of the invcntiomthe device i's operated by pressure of an abutment against an extraneous object, such, for eXample,\as the bobbin or spool, as will hereinafter be more fully set forth.

Referring more particularly to the drawings, I have in the several figures repre- .sented a casing or housing lewhich may be of the genera shape disclosed in my said patent. Thercin, as shown most clearly in Fig. 4, I secure a bracket 2 into which is tapped a stud 3, the outer end 4 whereof passes through an opening 5 in the wall of the housing, thereby providing a bearing at the opening 5. The stud 3 is preferably provided with a groove 6 to receive a screw driver by which it may be secured in position. Itevolubly supported upon the stud 3 is a bushing 7 fast upon which is a needle carrying member 8 provided with beveled teeth 9 adapted to mesh with similar teeth 10 upon a second needle carrying member 11 provided with a bushing 12 revolubly mounted upon a stud 13 supported by the framing, whereby upon the actuation et the bushing 7 the needles are operated as hereinafter set for-th.

The needle carrying members 8, 11 are provided with hooked needles 14, 15 gener-V ally similar to those shown in my said patent. Each of them is,- however, cut away as indicated at 1G, 17 in Figs. l2 and 13, so as to render them resilienty and to insure the binds ing thereby of the thread ends,ashereinafter set forth. In order to impart rotative movement to the bushing 7, I provide the same nient. is at l sitioned that it is outer Thiais7 grasping with a lever arm 18, shown most clearly in ig'. 33 and provide means operatively connected with said arm and adapted to 'engage extraneous object 'to move said arm. Herein for the purpose l have .represented the casing l as having e, casting or bracket i9 secured thereto and having extending therefrom. a generally cylindrical portion 20 rc ceiving a similarly shaped member 2l, the outer end 22 of which is herein shown recessed for the reception of aleather orother 'plug 23, herein shovvn as secured in position by a screw 24 tapped into a transverse partition 25 of said member 2l. The member 2l. constitutes a plunger or abutment, and is provided with a pin 26 adapted to slide in a slot?? in the member 20 and pivotally connected to a link 28, itself pivotally connected at 29 to the arm 18 of the bushing The end 23 of the plunger constitutes a head that is blunt and @if that it may engage an extrzfmeous object for the purpose stated, Without injury to the device or to said object.

l1 maygit desireda provide the casing` i with a rigid bracket 30 which if desired may be grasped by a forelinger when the hand is placed about the handle 31 which, as herein,

shown, depends at a downward inclination f from the casing 1.

The operatoria use grasps the handle 31 in the palm of his handand if'clesired ilaces his oretlnger about the hook or bracket 30. the device, he presses the end of the plunger or abutment 2l against some extraneous object, such as the spool or bdo bin and thus moves the needles lll, l5 Werdlyfso that they cross eachlother dis,- in my said patent and asv indicated in Athe several views'.

/Tie'xving Figs. l and 39 it will be observed it the or abutment protrndes om the body ci the knot tying device above handle andelso at a point substansairrhandle. so that when the tot tying; device is brought int@ with an extraneous object, the ty is Wholly'removed o1'..g1ea.tly less ened oi' twisting or unbalfencing` said device. Moreover the axis of said plunger or abutsubstantially right angles to the ris of the ha`ndle 3l, so that the strain of `)act of said abutment against the entranoons object is'transmitted in the most satis-- t story manner to the said handle. llurthei"`- more the .said abutment or plnngei is so peclearly visible to the user when the. knot tying device is held in the hand in position for use. 'lhus, the userlnay Apresent said abutment orplunger to the desire@ extraneous object without fear or :danger of damage to knot tying device or oft pressing or engahing the body of said niet ying devicenfith the` extraneous object -rot-li er than the abutment.

but a rigid member 30 substantial area, so

Viewing Fig. 3,

menace it Will also be observed that the shaft 4 carrying` one of the needlesv has a projection i8 which prior to actuation of the device lies in a 'path substantially normal to the path of movement of said. plunger or abutment 2l. ln that form of the invention shown in Fig. 3, there is provided not only the handle 31 which may be grasped in suitable manner as by the loretinger. These two handles 30 and 3l are preferably separated to substantially the extent shown, thus giving the two point support and Wholly resistingthe strain to which the lrnot tying device is subjected by impact or engageinent of the abutment 21 with the extraneous object. rlfhese and other results are secured by the employment of an abutment or plunger as herein disclosed. The abut-- ment projects from the body of the knottying device opposite to the handle thereoic and across the body from said handle, there by to provide a' balanced structure in operation. Furthermo@ the objectengaging portion of ,said abutment is symmetrically positioned with, respect'to the supporting means on the body lor said abutn'lent, there` by to facilitate the proper action of the abutment and the operative means controlled thereby llhe knot tying device is provided with non-securing, hand grip means herein embodied in the handle 31.. The said handle is more lirmly held by the clenched thumb and fingers of the hand than is the case of a knetter which is strapped to the hand, so as to be Worn constantly thereon, and leaving the fingers oit the hand to which the knetter is attached `free to engage 'the bobbin having the broken thread. A Firm grip upon the iandle 3l is of great importance since the device intended to be operated by forcible change of position thereof through the aid of said grip means, and preferably by .movingthe piston 23 forcibly against an extraneous object. W ere the liandle 3l not eectively gripped, the device would be so turned in or upon the hand as to interfere markedly with or wholly to prevent'th'e proper operation of the knot tying mechanism.

ln order to return the needles to their normal or inactive position, l may provide any suitable means. but preferably l attach t0 the casing or housing l a bracket 32, as most clearly shown in Figi. 3, and connect thereto one end of a coil spring 33, the other end thereof being` suitably connected to the busling` 7. lf desired and preferably l provide a stop 34. against which the brackettakes in the return ot' the needles to inactive p0sition. ln order to sever the threads Aand preferably so as to leave short, equal length ends, l have provided a n at 36 in the casingand hin/ingl spur teeth 37 adapted to mesh with similar teeth 38 upon the needle carrying member il7 as shown member 35 pivotedv les most clearly in Figs. 4 and 5. The said member. 35 is provided with two cutters indi- 4cated at 89, 40, which co-act respectively with stationary cutter members 41, 42, shown mosto early respectively in Figs. 5 and 6. The two threads are positioned-in the device in a manner generally similar to that l shownin my said patent.

the said thread, and is then Wrapped about the needle 14 moves.

the posts 47, 48, preferably similar in form l`and function to the corresponding post, shown in my. said patent and between which The thread b in its l course about the post 47,48 is passed under lat and then over a yielding/hook-like member 49 pivoted at 50 upon the casing and generally similar to the corresponding part shown in my said patent. In practice the thread b that is looped about the post 47, 48 is drawn tight so as to snap /of the hook-like inem- The construction and positioningI of the cutters is such that upon' thread severance the thread ends are of .substantially equal length and are quite short.

An important feature of my invention consists the provision ofv means whereby each of the needles binds the end of its thread-against a surface which is preferably the easing, so that after the threads have i *been looped into knot form, as indicated at c vin Fig. 11, but prior to the tightening of the knot, 4the said threadv ends are held so that as the threads or untightened knot are drawn out of the device, as, -for example, by the further rotation of the bobbin or spool carrying one of the threads, the knot is vtightened against the resistance afforded by the said binding action. The binding action is preferably secured by the heads of the needles, Y and in Figs. 12 and 13 I have represented' theineedles 16, 17 as respectively having heads 51,52, which act to bind the thread Aends as therein represented tightly against "the needles 'secured by cutting them away as indicated at 16,- 17 assists in the said binding action, vwhich is an important feature of my invention. The device,x when not in use., may

be supported in any. suitable manner For this purpose I preferably provide the framing adjacent the upper end of the handle 31 with an eye 54 adapted to be received upon da hook 55 of a strap-like me ber 56 shown in part in Fig. 14, and whit may be supported about the neck of the opcrativewith the portion 57 thereof in convenient position for receiving thc knot-tying device. t

It will be clear from the foregoingrdescription that' the knot tying device herein disclosed is not secured to the' hand of the operator and that I do not prlovide means for manually operating the device to form a knot. On the contrary, the needles by which the knot is tied are operated by the abutment or plunger which is placed by the opcrator in contact with some'extrancous object 'and preferably by pushing the saine against such object, though it will be evident that within the scope and purpose of my invention the plunger or abutment might be operatedby a pulling action thereof, or any other suitable movenirnt. The cutters are actuated in their cutting movement by the inward movement of the plunger 21 and sever the thread ends close tothe knot and so as to 4leave equal lengths.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being Set forth in the following claims.
